Just the job for extreme environmental conditions.
 |
The VARISTAR electronics cabinet must operate in accordance with the requirements of all situations. It has therefore been designed such that you can depend on it one-hundred percent even under extreme environmental conditions. After all, it is reliability, down to the last detail, that makes complex safety tasks achievable - and also economic. |
Two load classes, one cabinet
 Slim-Line. The special Slim-Line extruded profile is capable of a static load-carrying capacity of 400 kg with a minimum of materials, and satisfies the DL5 and DL6 requirement classes of IEC 61587-1 for dynamic loads. |
 Heavy-Duty. The robust Heavy-Duty frame was specially designed for high load-carrying applications. Thanks to its higher bending stiffness it can accept a static load of 800 kg, while under dynamic loads it satisfies classes DL5 and DL6 of IEC 61587-1. Dynamic tests also demonstrate earthquake resistance up to zone 4. |
Vibration and shock resistant.
Shock absorbers.
For still higher resistance to shock and vibration, VARISTAR solutions can be further equipped with SOCITEC shock absorbers.

These characteristics are of particular importance for mobile applications on board rail vehicles. Both VARISTAR profiles, Slim-Line and Heavy-Duty, protect their electronic systems with their high mechanical stability and dynamic load-carrying capacity exactly as your application requires, thus making an important contribution to the safe and problem-free functioning of the overall system. |
Long-term service.
 |
VARISTAR remains unfazed even by unfavourable conditions such as humidity and dirt. Zinc-plating and additional powder-coating provide a double protection against corrosion. |
HF shielding and IP protection.
 |
The VARISTAR shielding principle protects sensitive data from interference radiation. Tested to IEC 61587-3. The HF gasket simultaneously forms a barrier against dust and water to IP 55.

Variable cabinet cooling up to 40 kW.
Scaleable, modular and energy-efficient: with our cooling solutions you are playing safe. Our VARISTAR LHX programme, for example - our complete solution with integrated heat exchanger - excels with its high energy efficiency and high cooling capacity. This means that the cabinet can be cooled using the smallest possible floor area and with minimal energy use. And with a lower noise level. VARISTAR LHX also gives you up to 20 % more space in comparison to other cabinet solutions.

Depending on the amount of heat generated and the internal and external temperatures, various cooling concepts may be applied to keep electronics cabinets effectively cooled. These may use air-filtered fans, fan trays or controlled airflow systems through to air/air or air/water heat exchangers and compressor-driven air conditioners. |
